As clearly seen in Figure 1 of thedrawings,

the internally threaded shank 17 is adapted for the reception of the screw stem 5. A suitable anti-friction bearing y23 rests onV the upperV side of the internal flange 14- in the lower end portion ofthe neck 18 and the coil spring v2li encirclesthe shank 17 and has one end engaged'with the'hubportionfQO of' the Wheel 19 in a mannerto yielding'ly urge said hub portion and wheel, they shank 17, thek piston 15A and Ythe sealing ring 18 npwardly tol provide a leakproof jointr between the In operation, the blandv Wheel 19.V is rotated,;thus rotating the' internally threaded ^shank 17 and the piston 15. `The screw s tem 5 is'retained against rotation by the head 4 and vtherefore will Ibe threaded into and out of the shank 17 upon rotation of said shankVY '17, las will-be readily apparent. `The packinglrings 16 prevent'practically all leakage pa'stthe piston 15 and the sealing' rings 12 and `18'willarrest any fluid which may ge past the packingr-ings 16'.

,As wear takesplace onthe rings 12 and 18,

said wear willlbe compensatedfor by the action ofthe" coil spring-24 raising the shank *the piston'l and the ring 18 and keeping said ring 18'constantly'engaged with the ring It -is believed that the many advantages of a valve constructed in accordance with this invention will be readilyv understood, and althoughcthe preferred embodiment of the ring in a manner to'form a leakproof joint therebetween. l Y,
